Before you use this tool

Is the Scan Time Estimator free to use?

Yes. You can use this tool in the browser without creating an account or installing software.

How accurate is the Scan Time Estimator?

The arithmetic uses the values you provide. Its usefulness depends on whether those inputs represent the real drive, team or transfer conditions, so treat the result as a planning estimate.

Can this tool delete or change my cloud-drive files?

What should I do after using the Scan Time Estimator?

Allow extra time for throttling or resumptions. Actual duration varies with folder structure, Microsoft Graph responses, retries and account size.
